Question

Which among the following is (are) rational number(s) ?

• A. $\frac{10}{3}$
• B. $0.99099$
• C. $\sqrt{5}$
• D. $\pi$

Answer 1

Answer: (A), (B)

The correct options are
A $\frac{10}{3}$
B $0.99099$

$\frac{10}{9},0.99099$ are rational numbers as they can be expressed in the form of $\frac{p}{q}$ where $p,q\in Z$ and $q\ne 0.$

$\sqrt{5}\to$ square root of prime number $\left(5\right),$ so it is irrational.

$\pi =\mathrm{3.14592...}\to$ it is neither terminating nor repeating. So, it is irrational.
